Systematic is the choice of exacting professional photographers who use long lenses and heavy cameras. Not only are Systematic Gitzo’s strongest and most stable tripods, they’re also modular, with a top casting element that opens and closes to allow each tripod to be configured with a flat disk, geared or sliding center column, video hal adaptor, leveling base or other Systematic accessories. The latest range features Carbon eXact tubes, new ultra-stable feet and the Easy Link attachment, making the Systematic even more stable, versatile, and ergonomic. The Easy Link attachment (3/8'' thread) allows the user to attach various accessories such as a Manfrotto arm to use lighting accessories. Series 5 (top leg diameter 41.3mm) is the choice of the most demanding professionals, being the most rigid tripods in the whole Gitzo range. The top casting is larger than that of Series 3 & 4 Systematics in order to provide maximum stability. GT5543LS is the 4 section long model, a size very popular for its balance between closed length and sufficient height even without a column. It replaces the GT5542LS. specs Units: Imperial| Metric Weight 2.82 Kg Top Attachment 3/8'' screw attachmenttype Bubble Spirit Level (no.) 1 number Carrying Bag Included none Centre Column no centre column Closed Length 60 cm Colour Noir Decor color Easy Link Yes Leg Type Single Leg Angles 26°,55°,89° Leg Lock Type Twist Lock Leg Section 4 number Legs Tube Diameter 29,32.9,37,41.3 mm Material CarbonExact Max Height 156 cm Maximum Height (with Center Column Down) 156 cm Maximum Working Temperature 70 degC Min Height 10 cm Minimum Working Temperature -30 degC Safety Payload 40 kg Upper Disc Diameter 90 mm
